Paragrilus fallorum Hespenheide , new species

( Figs. 13 , 29 )

Holotype male: Agriliform, moderately flattened above, black throughout, except head with faint golden reflections, pronotum reddish­coppery, elytra with fainter coppery reflections; 4.05 mm long. Head with front convex, impressed along midline on upper 2/3 more narrowly above, widening below; epistoma slightly depressed between antennal insertions and below fine V­shaped groove, ventral margin distinctly produced, quadrate, shallowly emarginate, angles acute; surface finely punctate, shagreened. Pronotum somewhat flattened, widest near apex; prehumeral callosity small but strongly indicated by broad lateral depressions; prehumeral callosity produced outward and anteriorly to form narrow ridge above and roughly parallel to marginal carina; anterior angles rounded­angulate; disc strongly depressed along midline at basal margin before scutellum and less strongly so at base of lateral depressions, slight depressions on either side of midline near apex; surface finely punctate, strongly shagreened. Elytra with posthumeral carina extending somewhat beyond hind coxae, surface coarsely rugose, with indistinct costae; apices broad, roundedsubquadrate. Posterior angles of hind coxae acutely rounded, depressed. Anterior process of first abdominal segment without carina posterior to hind coxae. Male genitalia reddish brown, with transparent tips to lateral lobes ( Fig. 29 ).

Allotype female: 4.3 mm long; not otherwise dimorphic.

Holotype: Panamá: Canal Zone, 5 mi SW Gatun, 09° 14’ N 79° 58’ W, 7.X.1969, H.A. Hespenheide, on Heliocarpus ( USNM).

Allotype: Same data as Holotype ( USNM).

Paratypes: Panamá: Canal Zone, same data as Holotype (7, BMNH, CHAH, NMPC), Madden Forest, 27.VII.1969, H.P. Stockwell (1, STRI); Pedro Miguel, 27.VII.1972 (1, CHAH); Pacific Canal Zone, Balboa­Diablo, 4.XI.1972, D. Engleman (1, LACM); Gatun Spillway, 15.X.1973, D. Engleman (1, CHAH); Chiva Road, 21.XII.1975, Engleman (1, CHAH); 1 mi S Gamboa, 6.XII.1969, H.P. Stockwell (1, GBFM); Panamá Pr., Punta Chame, 5.XI.1975, H. Wolda (1, RLWE).

Host: Adults have been collected on Heliocarpus (Tiliaceae) .

Etymology: This species is named in honor of Louise and the late Richard Fall and their long term support of field and taxonomic entomology ( Evans et al. 2001).

Discussion: This species is very similar to trifoveolatus , but apparently allopatric, and the characters given in the key distinguish it. Specimens vary from 3.6­4.45 mm in length (mean = 4.10 mm, N = 16). Although most specimens are bicolored as described and as discussed under P. trifoveolatus , two specimens are a more uniform greenish­brassy.
